Proposal:

Thebase64 module contains implementations of encoders/decoders for several character encodings.

Among these are the base32 and base32hex encodings mentioned inRFC 4648.

These are currently implemented in pure Python. Implementing them in C will greatly improve performance (~100x) and memory usage.

I have written a draft PR that accomplishes this, and will be submitting it shortly.

Has this already been discussed elsewhere?
